Electron Diffraction

Purpose

1) To demonstrate the wave properties of electrons.
2) Examine the DeBroglie relation [math]\displaystyle{ \lambda = \frac {h}{\vec p} }[/math]
3) To measure the diffraction planes of graphite.

Theory

Equipment

  • Tel 2501 Universal stand
  • Electron Diffractor 2555 (5Kv .3mA)
  • Teltron Limited London England 813 KV Power Unit
  • HP 6216B Power Supply
  • Wavetek Meterman 85XT multimeter
  • Carrera Precision 6" digital caliper alloy

Safety

  1. The main safety concern during this procedure is electrical shock as high voltages will be used. Standard high voltage safety precautions should be taken, including checking all equipment for damage and ensuring the equipment is properly connected.
  2. The second concern is the integrity of the equipment. Most importantly, the graphite diffraction tube. As indicated in the lab procedure
